oEngineering Project Samples:

Post Doc Project – PCr recovery: This project was a medical study or the recovery or muscular PCr in patients in order to aid in the evaluation of physical therapy treatments. The project involved the analysis of PCr, PI, and ATP from MRI spectrometry scans. My role was to determine a recovery rate of patient levels. The project used MRI scanning protocols, Data collection, analysis of spectrometry data, development of analysis programs and algorithms, and evaluation of the data. The project used Siemins MRI, Jmrui, python, MATLAB, Excel, and DICOM processing skills.

Magnetic Particle Detector Medical Device for Graduate Thesis: This project was designed as the invention of a portable medical device capable of detection magnetic particles for use in triage medical diagnostics. The project was taken from initial concepts to prototyping and fabrication phases and was done completely by myself with the guidance of my principal investigator Dr. Jeffery Walton. The project included aspects of simulation modeling, fabrication of coils, analysis and development of magnetic fields, invention, functional analysis, computational analysis, programming, Data collection,signal manipulation and analysis. The project used CAD, Machine Shop Skills, MATLAB, benchtop fabrication, network analysis, Signal Amplification, filtering, Lock-In amplification, tuning and matching, mechanical and biomedical engineering, Design control, product design, mechanical design, product development, product documentation, lean manufacturing, manufacturing engineering, wiring, electrical design. Patent and Publications pending

Electro-Magnet Project: As part of the UC Davis Preparatory course for Biomedical Engineering Senior Design, this project was conceptualized, created, and worked independently on by myself. The vision on this project was to remove short comings in the current project, motivate students to work independently, and serve as an all-around fabrication project designed to expose Undergraduate students to the skills needed to start their senior design project. The proposed devise was a handheld electromagnet tool. The project would expose students to the concepts of making 3D CAD models, reading and making technical drawings, and use an array of heavy machine shop tools including: Lathe, Mill, Drill Press, 3D printing, Laser cutting, Welding, circuits, magnetic induction, injection molding, wiring, electrical design and overall fabrication. This project included project planning, cost analysis, risk management, instruction management, and mechanical engineering design, product verification. Technical Drawings available upon request. Final device was determined to be a decrease in cost, and addressed concerns in the current project schedule. Used mechanical and fabrication skills, Design control, product design, mechanical design, product development, lean manufacturing, manufacturing engineering.

Endoscopic Collection Probe - Lost Leonardo Project: This project was designed to determine the existence of a lost Leonardo painting (The Battle of Angharad) behind another masterpiece in Florence’s Salone dei Cinquecento (Hall of the Five Hundred). Under the directive of Dr. Nate Delson (UCSD), my assignment involved modifying a forceps clamp (used in an endoscope) to collect a paint sample for analysis. The clamp modification I invented was an attachment to an available medical device forceps and had several key features: it could be switched from one clam to another (adaptive), it had few moving parts and could be simply operated with a single hand, the clamp attachment was easily replaced and constructed with low need of specification tolerance with cost effective materials, and the design reduced the risk of dropping the sample by having a single action switch that remained closed when triggered until intentionally released. Used mechanical and fabrication skills, Design control, product design, mechanical design. Final Device worked as desired (

Dental Nitrous Mask Nasal Canul: As part of the UCSD Bioengineering Senior Design Project, this industrial design project was commissioned by La Jolla Dentist Dr. Lori Nettleton. This project was to redesign a medical device dental nitrous oxide mask to address concerns found in practice. This project required problem analysis, risk analysis, design alternatives, 3D computer modeling, fabrication and performance testing. Used mechanical and fabrication skills Design control, product design, mechanical design, Data collection, product development, lean manufacturing, manufacturing engineering. The final product was determined by be similar in performance to current medical devices but at less than half the original cost. (

Ball City Robot: As part of the UCSD Graphics & Design Project, this project was a robotic competition to collect balls from an acrylic playfield simulating a city scape. This project involved design, risk analysis, testing and construction (from steel and acrylic) to build a robot that collected balls with a claw and placed them in a bucket while blocking other robots with webbing shooter. Using conservation of energy and momentum, spring energy, motors, gear ratios, linear sliders, and dampening forces, the compact robot unfolded into its final form to accomplish its desired function. Used robotics, mechanical, and fabrication skills. The final design was able to function, although was eliminated in the contest (
